DMS Series meters indicate negative input signals by turning ON a minus sign display-segment ("-") located to immediate left of the half- digit. Positive inputs are indicated by turning OFF the minus sign segment. For example, "-1234" is displayed for negative inputs, and "1234" for positive inputs. The minus sign is ON when IN HI (pin 11) is slightly more negative than IN LO (pin 12). Operation of the minus sign is automatic and can not be externally disabled by the user.
